IMPROVEMENT IN BoLTlNG-REELS.

Specification forming part of Letters Patent N o. 184,878, datedNovember 28, 1876; application filed October 5, 1876.

To all whom it may concern:

Be it known th'at I, FITOEB. LEwTs, of Tiffin, in the county of Senecaand State of Ohio, have invented a new and useful Improvement inBolting-Reels, which improvement is fully set forth in the followingspecification, reference being had to the accompanying drawings, inwhich- Figure lis a longitudinal vertical central section of my improvedbolting-reel. Fig. 2 is a vertical transverse section of the same, witha fuller illustration of the knocking' or jarring hammers and theiradjuncts. Fig. 3 is a detail view of the coupled adjustable cams,whereby the knocking or jarring hammers are operated. Fig. L,tis adetail sectional view of an india-rubber friction-roller used on thelever-arms of the hammers. Fig. 5 is a detail sectional view of anindia-rubber hammer used for jarring or knocking the reel.

The nature of my invention consists, first, in the-employment ofindia-rubber hammers or knockers, instead of metal hammers, in abolting-reel; it consists, second, in the employment of india-rubberanvils in a boltingreel, instead of iron anvils; it consists, third, inthe employment of india-rubber frictionrollers in a bolting-reel,instead of metal rollers; it consists, fourth, in a pair of coupledadjustable lsymmetricallyarranged cams, whereby the hammers and rollersof a bolting-reel are operated in a peculiarmanner; fifth, in animproved manner of fastening the india rubber hammers Ato their leverarms 5 sixth, in an improved manner of providing the india-rubber with ametal bearing or box; seventh, in the peculiar construction andarrangement of the said parts, whereby a-number of successive blows aregiven in a horizontal and alternately opposite direction upon the barsof the reel.

The objects of my invention are, mainly, first, to improve the operationof the boltingreel by avoiding the sharp and insuiiicient blow of aniron hammer upon an iron anvil, and to give a blow which possessesgreater transmitting power, and, at the same time, to avoid the dangerof breaking the parts by the concussion upon the rubbers, and by thefalling of the hammers and rollers upon the bolting-cloth, and to lessenthe noise or rattling' of the reel. A second object is to givesuccessive blows in opposite horizontal directions; and a third and lastobject isl to make the machine easier to operate.

In the drawings, A represents the casing of a bolting-reel, and B thebolting-reel, constructed in the ordinary manner, and preferably in theshape of a hexagonal skeleton prism, with six longitudinal bars, b, andarms b', fastened to an axle, C, which has journalbearings c in thecasing A. Every other one of the said bars b is provided with afulcrumbearing, d, for the lever-arm D of a hammer, E. The said hammer Eis made of india-rubber, and fastened between two washers, e, by meansof two nuts, e', upon the lever-arm D, which, for that purpose, isprovided with a continuous screw-thread, d', the back nut being screwedup to the end of said screwthread, and thus prevented from moving.

At the other sidepof the bearing d the lever-arm D extendsA in shape ofanother arm, D, through a coupling-clamp, F, which has a longitudinalrod, G, fastened toit by means of a set-screw, f. The rod Gis so passedthrough. the clamp F that it touches the lever-arm D', which therebybecomes fastened by fastening the rod G with the screw f. v

The rod G extends to the discharge end of the reel, and opposite anddirectly in line with the bearing d is secured, by a bearing, g, on thesame bar that holds said bearing d. On the other side of the bearing gthe rod G extends into a lever-arm,G/, with an indiarubberfriction-roller, H, at its end. The

'roller H is mounted on a tube, l1., with. a

flange, h1, upon which tube another fiange or washer, h2, is fastened,with the roller H between it and the flange h1.

The lever-arm G is bent at a right angle near its end, and the roller Hput on it, whereupon the end is riveted to prevent the roller fromslipping off. At a suitable place the arm G is provided with atension-spring, I,

the free end of which is fastened to thefreel.'

At certain intervals the rollers H are met by cams K K1, over which theytravel, and by which they are swung outwardly. The cam K is pivoted atlo to the head of the case A. The cam K1 is pivoted at k1 to the samepart, but on the other side of the axle C, and

-a horizontal position, so that each revolution of the india-rubberhammer shakes the whole Vthe parts which were brought in contact.

the eccentric outlines of both cams are symmetrical when in operatingcondition, so Vthat the cam K points up, and the cam K1 down. The cam K1has an upper lever-arm, K2, with holes 7a2 for the attachment of anoperatii'g'N cord, X, and a coupling-link, L, connecting it with theupper part ofthe cam K.

The bars of the reel which are struck by the hammers are provided withindia-rubber anvils E', which relieve and protect them from directwearing action of the hammers. The anvils might, in some cases, bedispensed with.

The axle O may, at one end, be provided with a pulley or with a crank,for the application of either machine or hand power.

Operation: rlhe reel, provided with bpoltingcloth, and chargedwith our,is set in motion, and the cams K K1 are moved by the cord X in thepositions shown in Figs. 2 and 3 by dotted lines. The rollers `H arethen forced to mount the said cams atieach revolution of the reel. Theroller H, by traveling over the cam K or Kl, is swung back, and thetherewith-connected hammer E removed from its anvil E', or from the barof the reel. Arrived at the end or highest point of the cam the roller His left without support, and is suddenly drawn back by the spring I,therebyr forcing the hammer upon its anvil, or directly upon thereel-bar in case no anvil is provided. The said blow occurs when thehammer is in of the reel causes two blows of the same hammer in oppositedirections, and as there are three hammers, there are six blows to onerevolution of the reel, and all these blows are given at equal intervalssuccessively. The reason for having the blows in a horizontal directionis this: that the our brought down from the cloth by such blowisdeposited upon the inclined sides ot' the cloth, and does not interferewith the our upon the horizontal part of the cloth, n'or strain thecloth by the impetus of its fall, While the inclination ofthe otherparts breaks the force of such fall, and gives the iiour at once thenecessary motion upon the cloth.

The india-rubber hammer gives a (leader blow than a metal hammer, theblow of the latter being sharp and short, and therefore wit-houtcommunicating power, while the blow reel, without snapping the slatsasundernor loosening their connections, because the yielding nature ofthe india-rubber prevents the spending of the whole force of the blow atonce, and retains a portion thereof` as accumulated force, to beexpended at the rebound of By using a rubber roller, H, I avoid theannoying rattle caused by its meeting with and leaving the cams K K1. Ialso modify the concussion `of'the said. parts in such degree that theirconnections and bearings are much less affected or disarranged.

4In cold weather metal (and especially iron) becomesfbrittle and` breakseasily. In such case a broken hammer will, by its weight and the sharpedges of its fracture, tear up the The same is the case if aboltingcloth. 1 metal roller breaks or becomes disconnected. Anindia-rubber hammer or roller is, on account of its lightnessy not soeasily detached from-the operating-lever, either by breakage or gradualgiving way of the fastenings from jar, and, if broken, their littleweight and yielding.consistency-in volve no danger to the preservationof the bolting-cloth.'

The manner of fastening the india-rubber hammer admits adjustment,sothat the'said hammer may be more or less forcibly clamped between theWashers,` and thereby give a blow more or lesshard or bounding.

. The manner ot providing the india-rubber,

roller with a metal bearing is also susceptible of adjustment, inasmuchas the roller, when working loose, can easily Vbe clamped tight byforcing the washer closer toward the dan ge of the tube, and then andthere riveting it upon the tube.

Having described my invention, what I claim as new, and desire to secureby Letters Patent, is-

y 1. A bolting-reel having knocking-hammers of india-rubber,substantially as and for the purpose set forth.

2. The combination, with a bolting-reel, of

knockinghammers, arranged to give a snccession of blows laterally andalternately in opposite directions, substantially as and for the purposeherein set forth.

3. A bolting-reel having friction-rollers of india-rubber between thetripping mechanism` and the hammers, substantially as set forth.

4. The combination of a bolting-reel with jarring or knocking hammersand the coupled` `cams K K1, substantially as and for the purpose setforth. l

5. The combination of the india-rubber hammer E, the washers c, nuts e',and lever-arms D, substantially as set forth.

6. The combination of the roller H, the flanged tube h, and the washerh2, substantially-as set forth.
